Light emitting diode (LED) lighting fixture

摘要

A high power lighting fixture which includes a first multiple of first light emitting diodes (LEDs) mounted and series connected to form a first serial string of LEDs on a first circuit board. A second multiple of second light emitting diodes (LEDs) mounted and series connected to form a second serial string of LEDs on a second circuit board. Mating circuit board connectors are mounted on the first and second circuit boards. The first and second LEDs, the number of first and second LEDs and the current supplied when operating the first and second LEDs are selected so that the lighting fixture is operable at a minimum electrical power rating of 100 Watts. A control signal is received which determines current division between the first and second LEDs.

主权项

1. A high power lighting fixture comprising:
a first plurality of first light emitting diodes (LEDs) mounted and series connected to form a first serial string of LEDs on a first circuit board; a second plurality of second light emitting diodes (LEDs) mounted and series connected to form a second serial string of LEDs on a second circuit board; wherein said first LEDs and said second LEDs have different spectral emission characteristics; mating circuit board connectors mounted on said first and said second circuit boards wherein said mating circuit board connectors are adapted to connect said first and second serial strings in parallel; and at least one device mounted on at least one of the circuit boards, wherein the device is adapted to receive a control signal, wherein based on the control signal said device determines current division between the first and second LEDs, wherein the first and second LEDs, the number of first and second LEDs and the current supplied when operating the first and second LEDs are selected so that the lighting fixture is operable at a minimum electrical power rating of 100 Watts.
